January 2025

Happy New Year Friends,


In the month of new beginnings, we bring you some exciting ones! In this eNewsletter you'll learn about new fieldwork plans at a site we are anxious to preserve fully - Rattlesnake Canyon! As well as plans for baseline documentation at sites we have not yet visited - sites that will be digitally preserved for the first time.


I am also thrilled to share that field work and lab work for the Hearthstone Project have been completed! Publications are in the works and we truly believe that what has been revealed through the work of this project will change the way the world views this unique and sacred region of Texas and Mexico.


If you missed our Hearthstone Project Results Lunch and Learn Series, you can watch on YouTube.


Thank you for your interest in the rock art of the Lower Pecos Canyonlands and in our efforts to preserve, study and share the sacred Indigenous paintings. We need you with us to make our mission possible.

Wishing you all the best this new year,

Jessica

Hearthstone Project

COMPLETE

It is hard to believe that over three years have passed since I first introduced you to the Hearthstone Project in our October 2021 eNewsletter.

In that eNews, I answered FAQs including:

  • Where did the project begin? With the Alexandria Project and the three Co-Leads, Drs. Karen Steelman (Shumla), Carolyn Boyd and Phil Dering (Texas State).
  • What are the goals of the project? To investigate when and how the murals were painted and what they mean.
  • How long will project take? Until the end of 2024.
  • Why is it called "Hearthstone?" After the hearth fire and the comal supported by three hearthstones. Our research was supported by: (1) archaeological science, (2) formal art analysis, and (3) Indigenous knowledge.


Now, in January 2025, we are so pleased to report that the field and laboratory work for the Hearthstone Project is done!


Three things follow field and lab work in the world of archaeology.


1) Writing… writing… writing up the analysis and conclusions for presentations, publications and release to the scientific community and the public.

Mesoamerican cosmological concepts originated from an Archaic core of beliefs that persisted across time, cultural, linguistic, and geographical boundaries. Our Hearthstone Project publications will reveal the date, extent, and location of the oldest known graphic expressions of these concepts. We will share our publications as they are published. 


2) Curation of every single piece of data and every image


Shumla's archive of data and imagery will be the way people study, enjoy and engage with the rock art of the Lower Pecos for generations to come. We take data preservation very seriously.


3) Planning for what's next! Applying lessons learned. Updating project/research designs. Getting back out there!


We are currently updating our research design based on lessons learned and will soon begin to apply these lines of investigation to new sites as we continue to preserve and study the rock art panels of the Lower Pecos. We have already received permission to apply this method to one of the most endangered and most complex sites in the Lower Pecos – Rattlesnake Canyon! More on this below!



Hearthstone Project

Graphic Databases

The final Hearthstone Project task for Shumla's Preservation Archaeologists Dr. Diana Radillo Rolón and David Keim was to complete an iconographic study of each of the 50 painted figures from which radiocarbon samples were taken. This included carefully sketching the figures to match their current state of preservation, color matching to ensure the accuracy of the image, color layer ordering based on digital microscopy to follow the original paint sequence, and adding data locations of microscopy and radiocarbon sampling to highlight the information collected during the project. We call this a "graphic database." (I talked a bit about this process in our November 2023 eNews.)

As the project and the year ended in 2024, Diana and David worked diligently to complete these graphic databases with the help of our Shumla interns, Robert Stein and Summer Seigler. Together our San Marcos interns worked on 23 illustrations! Their hard work and dedication helped us finish all of our illustrations by our deadline. We now have completed and archived all 50 illustrations for the project.


Thank you, Summer and Robert!

Planning for the New Year

The Shumla team has been meeting in the San Marcos office to plan upcoming fieldwork and curation. We have big plans for 2025!  

1. RATTLESNAKE CANYON


Yes! The time has come.


For those of you who have been with us a while, you know that this site had been our Mount Everest. It is a massive (105 feet long), incredibly complex masterwork. Tragically, it is directly impacted by flash flooding.


In 2014 and 2015 Shumla undertook a joint project with the National Park Service and the site's owner Texas Tech University to document a portion of the site. Shumla conducted full figure documentation for 50 of the over 300 figures. Then in 2020, as part of the Alexandria Project, we completed Level 1 – Baseline Documentation at the site. (In the image below the team is holding a sign that shows Rattlesnake Canyon was the 177th site documented through the Alexandria Project). 


Now, we will conduct Level 2 – Figure Documentation and Analyses and Level 3 – Graphic Database Production. Shumla Preservation Archaeologists will complete photography, illustrations, descriptions, and attribute data for the remaining 250+ painted figures at the site. In addition, we will conduct digital microscopy at hundreds of locations of intersecting and overlapping paint colors to diagram the paint stratigraphy and determine the order the paint was applied to the rock shelter wall. We also plan to conduct chemical analyses, including radiocarbon dating.


Through this effort, we will learn as much as possible from this threatened site before we lose it to weathering and flooding. Our goal is to collect sufficient data to be able to digitally, or even one day to physically, re-create the rockshelter (like they have at Altamira, Chauvet and Lascaux) to preserve these sacred Indigenous paintings.

2. LEVEL 1 - BASELINE DOCUMENTATION


Did you know that there are over 350 known rock art sites in the Lower Pecos? Shumla has completed baseline documentation at 255 of them. There are still 100+ to be preserved. Our team is working with private landowners to continue baseline documentation at sites that we have not yet visited. So far, we have documentation planned at at least 5 new sites in 2025.

3. DIGITAL CURATION


Shumla Curator and Data Manager, Kelsie Hart, also has big plans for this year. Last year, she compiled an informative white paper exploring strategies for the curation of Shumla’s large digital data set. Over Shumla’s 27 years of operations, we have collected vast terabytes of digital data including all of our images, 3D models, and rock art documentation. These born-digital assets need specialized care to ensure that they remain accessible for future generations. Shumla’s curation goals for this year include finalizing a plan for digital curation so that we can begin fundraising and implementation in the years ahead.


Texas Historical Foundation Grant Project

Did you know that Shumla also curates archival collections? In addition to our digital data, we curate paper records, photographs, and maps related to rock art sites in the Lower Pecos Canyonlands. These legacy collections tell the history of rock art research in the region and help us evaluate the condition of rock art sites over time.


The Texas Historical Foundation has generously awarded Shumla grant funds to create a dedicated collections storage room at our San Marcos office and purchase archival supplies. The grant will also support a new photo scanner to digitize our legacy collections and one day make them available to the public. Stay tuned for more updates about this project in 2025!
